Tried replacing rear-facing camera

So I tried replacing my rear-facing camera, because I can't afford a new phone. Bought all the components and a repair kit. I did everything pretty much exactly as I was supposed to, but when it came time to remove the physical camera, I accidentally removed the gold thing to the direct right of it (there are two, one on either side of the camera---see photos). The gold thing appears to go back into place just fine, but it was connected by a black segment that I fear was an essential connective cable. Can someone confirm or deny this for me? I just want to know if I have any hope of the camera functioning once it's reassembled. (I haven't been able to test because I'm still waiting on my replacement battery.) I'm trying to decide if I should just replace the phone, or if there is hope that phone/camera will still work, even slightly. Thanks.
